With much thanks to Pat Irvine, I now have a copy of the death certificate of my great uncle Patrick CREEDON which states the following:
male/white/single Date of birth:March 6, 1875 Age:57 years, 7 months, 23 days Occupation:Bridge carpenter Birthplace:Grenagh Ireland Father:Daniel Creedon, born Grenagh Ireland Mother:Norah Cogan, born Grenagh Ireland Date of death:October 29, 1932 Place of death:Boise ID buried Morris Hill Cemetery?
According to my mother, my great aunt Margaret CREEDON came to the US at some point from Ireland and married Charles "Charlie" GLASS.She died in 1941 in Boise ID (buried Morris Hill Cemetery?).Charlie apparently worked on the Hoover Dam.Will send for death certificates and post update here.
Also, there was a second marriage for Michael CREEDON.He married Elizabeth "Lizzie" DONOVAN in 1913 in Colorado.
